The so-called "old man smell" is a reality that often arouses curiosity, discomfort, or even self-consciousness, both in those who notice it in themselves and in their elderly loved ones. This scent is linked to a series of biological processes, daily habits, and environmental conditions that develop over the years, and fortunately, there are natural methods and practical tips to neutralize it.
In this article we are going to discover in detail what they are the scientific causes of the old man smell, why it appears at a certain age, how to combat it effectively in both individuals and homes, and what habits can make the difference to always maintain a fresh scent. If you're concerned about this issue or looking for tips to eliminate it, here you'll find all the tips backed by evidence and experts.
Why does the old man smell? The scientific explanation
The famous "old smell", also known in Japan as kareishu, began to be studied in depth in the 2000s. Far from being the result of prejudice or simple perceptions, it has a biological and chemical origin that affects almost everyone over a certain age.
The main protagonist is a molecule called 2-nonenalThis compound begins to be produced in the skin when unsaturated fatty acids present in the skin's lipid barrier are oxidized. The fewer antioxidants we produce with age and the more lipids we have in our skin, the greater the production of 2-nonenal, and therefore, the more noticeable its characteristic aroma.
This smell is often described as a mixture of dampness, grass, rancid grease, and stale beer. Interestingly, 2-nonenal production can begin (very slightly) as early as age 30, although it intensifies after age 60. It is not only related to normal aging: certain conditions such as obesity, diabetes, stress, some medications, or hormonal changes can accelerate it.
According to various investigations, The smell of an old man does not depend exclusively on personal hygieneNo matter how clean a person or their home is, the interaction between sweat, skin microbiota, and lipid oxidation creates that scent that's difficult to remove with conventional soap and water alone.
Factors that aggravate the smell of oldness
In addition to natural aging and skin oxidation, there are several factors that can intensify the smell of old people:
- Lack of ventilation and environmental humidityPoorly ventilated homes retain the molecule 2-nonenal in fabrics, curtains, carpets and furniture.
- Excess dust: Dust acts as a reservoir for odorous compounds.
- Unwashed clothes or textile accumulation: Sheets, clothes and cushions store odors if not cleaned regularly.
- Stress and poor dietDiets poor in antioxidants and stress accelerate lipid peroxidation and the production of 2-nonenal.
- Skin changes related to certain chronic diseases, medications, or hormonal changes.
For this reason, Addressing the smell of old age should consider both personal and household hygiene as well as diet and general health.
Myths and realities about the smell of old people
The "old smell" is often associated with a lack of cleanliness or even neglect. However, scientific evidence contradicts this:
- It is not linked to poor hygiene habits, but to inevitable biological processes.
- It is not exclusive to older people:Young people with certain conditions may also notice this smell.
- It doesn't go away with frequent showers alone.It is necessary to use specific products and change certain habits.
This does not mean that it cannot be reduced or even eliminated by following a set of good practices that we will see below.
How to get rid of old man smell on your skin: effective tips
Combating old skin odor requires a comprehensive approach: choosing the right products, maintaining good habits, and, if necessary, incorporating natural remedies. Here are the methods that have been proven to be most effective according to studies and experts:
Soaps and specific products to neutralize 2-nonenal
- Soaps with persimmon extractThey contain antioxidants capable of neutralizing the 2-nonenal molecule in the skin. They are ideal for daily use.
- Stainless steel soapAlthough it may seem surprising, this type of "soap" (actually a stainless steel bar) eliminates persistent odors from hands thanks to a chemical reaction that traps sulfur compounds. It's reusable and effective after handling foods like garlic or fish, but it also helps eliminate strong skin odors, including those of the elderly.
- Moisturizing aloe vera soaps: They provide hydration and help regulate the skin's microbiota, fighting bacteria responsible for bad odor.
- Antiseptic soaps: They eliminate bacteria and fungi that increase odor. They can be complemented with antibacterial creams in prone areas (feet, armpits, etc.).
Homemade natural remedies
- Pure aloe vera gel: Applied after showering, it keeps the skin hydrated and reduces bacterial growth.
- Bicarbonate of soda: Mixed with water and talc, it acts as a natural deodorant thanks to its ability to alter the pH and create an unsuitable environment for bacteria.
- Apple vinager: Diluting one part vinegar with two parts water and applying to armpits, feet, or other problem areas fights fungi and bacteria without damaging the skin.
It is always recommended to perform a small patch test before applying any natural remedy on a general basis to rule out possible irritations.
Essential personal hygiene and health habits
- shower regularly, preferably with specific soaps.
- Pay attention to the areas where bacteria accumulate the most: armpits, groin, feet, neck.
- Waxing armpits and groin: Hair encourages the accumulation of sweat and bacteria that increase odors.

- Orange or lemon peels: Ideal for giving a fresh and natural touch to the home.
Habits and nutrition: the role of diet and lifestyle
Diet and lifestyle habits directly influence the production of 2-nonenal and the type of sweating. Therefore, A balanced diet and certain changes can make a difference in the long run.
- Prioritize foods rich in antioxidants (fruits, vegetables, nuts, fatty fish: omega-3).
- Limit saturated fats, ultra-processed foods, and sugars which accelerate skin oxidation.
- Avoid alcohol and tobacco: These habits increase oxidative stress and alter the composition of sweat.
- Drink enough water to keep the skin hydrated and facilitate the elimination of toxins.
- Practice regular physical exercise to improve circulation and stimulate skin renewal.
- keep a healthy weight helps reduce lipid accumulation in the skin.
Extra tips to prevent the old smell from returning
